PyCharm. /usr/bin/python^M: bad interpreter

Question

Cannot figure out, where to change EOF in PyCharm. My scripts, started with:

#!/usr/bin/python
# -*- coding: utf-8 -*-

Outputs something like this, when I try to run it like executable (chmode +x):

-bash: ./main.py: /usr/bin/python^M: bad interpreter: No such file or directory

What to do and how to be?

there seems to be `^M` characters in the script, use dos2unix — avasal, Apr 02 '12 at 10:50
It seems like the original file was created in MSDOS/Windows without UNIX/Linux end of line support. So when you tried to run this file on UNIX/Linux, you got an error. The easiest way is to recreate the file on UNIX/Linux. The scalable way is to configure the MSDOS/Windows shell to support saving with UNIX/Linux end of lines. It's help you to create and reuse files on both systems. — dzNET, Jun 29 '18 at 23:25

The issue is not EOF but EOL. The shell sees a ^M as well as the end of line and thus tries to find /usr/bin/python^M .

The usual way of getting into this state is to edit the python file with a MSDOS/Windows editor and then run on Unix. The simplest fix is to run dos2unix on the file or edit the file in an editor that explicitly allows saving with Unix end of lines.

I think the python interpreter is not ran at all. The shebang interpreter fails on ^M. – jpic Apr 02 '12 at 10:53

If you don't have dos2unix, simply execute `sudo apt-get install dos2unix`, in Ubuntu 14.04. – gsamaras Jan 30 '16 at 20:01

Set line separator to Unix:

If the file has already been saved, this doesn't seem help. Probably only with new files? You'll need to use the `dos2unix` tool for those files. – ksaylor11 Aug 02 '16 at 20:59

You may find the answers here: ./configure : /bin/sh^M : bad interpreter

As a Mac OS X user, I didn't find the command dos2unix. Alternatively, I use vi/vim: :set fileformat=unix and then save the file :wq

If you are using Vim, just enter the following command:

:set fileformat=unix

For MacOS you can install it via Homebrew like this:

brew install dos2unix

And next do

dos2unix FILENAME

Similar to Jiangwei Yu's post. On UNIX/Linux, I used vi to edit the Python file. Using vi, you can see the ^M at the end of each line.

Find the following line /usr/bin/python^M

Hit end to get to the end of the line

Hit delete to remove the ^M

To save the file and quit, type in: :wq

This worked for me.

you may try to do this:

sed --in-place 's/^M//g' main.py

[ to type in ^M, press ctrl+v,ctrl+m ]
